Audio Renderer vs. Audio Decoder
Hi everyone.
Can someone explain what the purpose is of both the audio renderer and the MPEG audio decoder? What functions does each serve and how are they different? I'm getting great video quality but I'm not happy with my audio quality. It sounds like it's distorted most of the time, especially at higher volume levels in a show or where there's lots of bass in the music. It's annoying! Thanks Skenz

Most audio is compressed (mp3, aac, mp3, ac3, ape, flac, wma, etc). In a very rough sense it's like a zip file (flac, ape, and WMA lossless are very much like a zip file).
An Audio Decoder uncompresses, or unpacks audio into it's raw form, PCM. Or sometimes, in the case of ac3 (DD or DTS) it will just pass the compressed data through. An Audio Renderer takes that raw audio and sends it, "renders" it, to your audio hardware (soundcard), where it is output. The same logic applies to Video decoders/renderers.

It sound to me that you have a problem with your Hauppauge card.
Try this tweak tool to adjust volume line in. http://www.shspvr.com/smf/index.php?...46415#msg46415 rtengvad

Hello - I keep trying to open this Tweaker program and Winzip keeps saying it is corrupted. I have tried different zip programs and downloaded it from different sites but I cannot seem to get the zip file to open.
What's going on? Thanks, Mike

I've done the zip it for you from my hard drive. See if it works that way.
